Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ostomy device of the type adapted to be adhesively attached to the skin around the stoma, and more particularly to excretion by internally sealing the stoma with minimal sealing pressure. The present invention relates to a device provided with a control means.

[0002]

2. Description of the Related Art Colostomy, ileostomy, and
Surgery, known as urostomy, creates an opening called a stoma in the abdominal wall. The stoma allows for waste disposal from inside the body cavity. However,
Patients undergoing such surgical procedures often have to utilize ostomy devices to protect the stoma and collect the waste to be discharged, as they have no control over waste disposal.

Over the years, a variety of different types and structures of ostomy devices have been utilized. Various materials and adhesives have been developed to improve the utility and wearability of ostomy devices.

The basic device comprises a collecting container or pouch connected to an adhesive-coated face plate. The face plate serves to attach the pouch to the body. The pouch is configured by sealing the first and second thin walls along the periphery by heat welding or the like. The pouch has an inlet opening provided alongside the stoma and may have an outlet for emptying material from the pouch. In one-piece ostomy devices, the pouch is permanently attached to an adhesive coated faceplate. In the two-piece type ostomy device, the pouch is detachably attached to the face plate by a coupling ring or the like. With the coupling ring and the like, the pouch can be replaced each time without removing the face plate.

The two-piece ostomy device requires a means for removably attaching the pouch to the face plate. 1
One particularly successful construction consists of a pair of annular or ring-shaped, rigid or semi-rigid, plastic parts, one of which has the shape of an axially extending rib,
The other has the form of a channel for releasably receiving and frictionally engaging the rib.

[0007]

These ostomy devices collect waste products excreted from the intestine, but do not include means for controlling when excretion occurs. One of the primary purposes of the ostomy device is to increase the freedom of movement of the user and the ability of the user to allow them to lead a more normal life by participating in various activities. However, in some situations, excretion into the collection pouch may confuse the user. This is because sounds and odors are generated and the pouch becomes large. Therefore, it is desirable to control when excretion occurs and to avoid situations that may cause embarrassment.

It is possible to temporarily seal the stoma to prevent excretion in some situations. However, sealing the stoma typically requires applying a large local pressure to the mucosal tissue. A high local pressure may abrade or damage the intestinal tissue, and if local pressure exceeds the local capillary pressure it may impede blood flow to the tissue.
Such consequences should be avoided.

It is desirable to prevent solid or semi-solid stool from flowing out of the stoma, but the same is not true for intestinal gas. Two thirds of the intestinal volume consists of intestinal gas. Intestinal gas is used for the comfort of the user.
And must be released to maximize the time interval between excretion.

It is also desirable that the sealing means be adapted to mate with a standard two-piece ostomy faceplate, and thereby replaceable with a standard two-piece ostomy pouch. On the other hand, the face plate must be removed each time a new sealing means is installed, but such a result should be avoided because such repeated removal may damage the sensory tissue or cause discomfort. .

[0011]

The above objects are achieved by our invention using a sealing means consisting of a balloon-shaped sealing member. The sealing member is received in the intestine and seals the stoma against excretion of solid or semi-solid stool.

The balloon-shaped sealing member exerts a low pressure (preferably 10 mmHg to 30 mmHg) over a wide range of the inner wall of the intestine near the intestinal entrance penetrating the abdominal wall. The seal member is made of a thin, flexible wall with one end closed and the other open. When the seal member is pressurized,
It expands like a balloon, sealing the internal intestinal wall with a large contact area. The flexibility of the wall of the seal member allows it to follow the intestinal wall. According to the results of preliminary experiments, the sealing member can prevent the release of stool from the intestine by increasing the internal intestinal pressure to 50 mmHg or more.

The wall of the sealing member is preferably made of a material which is also a good odor barrier. Polyurethane is used as a material for such a wall, but silicone rubber, a thermoplastic elastomer, or a widely known multi-functional barrier film can also be favorably used.

The sealing member can take various forms in order to maximize the sealing effect. One preferred shape has a relatively large spherical proximity to ensure full contact with the intestinal wall in the area near the abdominal wall.
The overall diameter and length of the seal member is also important and is selected to maximize the sealing effect for users of various body shapes and stoma shapes.

The seal member responds to a temporary increase in internal intestinal pressure by lightly contracting to equalize its internal pressure with the pressure in the intestine. The flexibility and non-rigidity of the seal members provide complete freedom of movement and the ability to follow intestinal pressure and local changes in shape.

The seal created by the seal member is intentionally mildly "imperfect" so that the intestinal gas present at the interface between the outer surface of the wall of the seal member and the intestinal wall passes along the interface. It is also. Solid or semi-solid materials, such as stool, cannot pass through the seal.

1 is an exploded schematic view showing the basic concept of an ostomy device according to the present invention. As shown in the figure, the ostomy device of the present invention includes a balloon-shaped seal member A. The seal member A is made of a thin and flexible wall body 10 having an opening 12 and a spherical proximity portion 13. The seal member A is adapted to be inserted into the intestine through the stoma 14.

The portion of the wall body 10 near the opening 12 of the seal member A is fixed to the inner surface of the top wall of the cap B. The cap B functions to hold the seal member A together with the opening 12 on the outside of the stoma 14 and to close the opening 12 of the seal member A. The cap B is made of a hard or semi-rigid material. The adhesive means C is provided to fix the bottom edge of the cap B to the tissue 18 around the stoma 14.

The cap B has an expansion port 20. A check valve or check valve 21 is connected to the expansion port 20. The check valve 21 may simply be a flexible flap, one end of which is fixed near the inflation port 20 and below the top wall of the cap B.

The expansion means D is a hand pump having a flexible valve 23 and a nozzle 28 made of a hard portion. A relief valve 25 having a conventional structure is connected to the nozzle 28 in order to prevent the seal member A from expanding too much. A small pump may be incorporated as an integral part of the cap B.

The nozzle 28 is connected to the expansion port 20 of the cap B.
, And the valve 23 is squeezed to inflate the seal member A. When the seal member A expands, it seals the stoma. When the nozzle 28 is pulled out, the check valve 21
Closes the expansion port 21 to maintain the pressure of the seal member A.

The seal member A is preferably made of a thin and flexible material and has good barrier properties. Polyurethane is one such material,
Silicone rubber, thermoplastic elastomers, or multifunctional barrier films can also be used successfully.

The sealing member A can take various forms in order to maximize the sealing effect. One preferred shape, as shown, is a relatively large tubular form with a spherical proximal portion to ensure full contact with the intestinal wall in the region near the abdominal wall. The overall diameter and length of the seal member A is also important. They are the basic factors in maximizing the sealing effect for users with different body shapes and stoma shapes.

Since the seal member A has flexibility and conformability, it is possible to cope with a temporary increase in internal intestinal pressure by making the internal pressure equal to the intestinal pressure by slightly contracting. To do. Since the sealing member A has flexibility and non-rigid characteristics, the movement of the user is completely free, and the intestinal pressure and local changes in shape are also followed.

The seal formed by the seal member A is
By design, it is mildly "incomplete". In that, the intestinal gas present at the interface between the wall of the seal member A and the intestinal wall can pass along the interface. Solid or semi-solid substances, such as stool, are impenetrable.

The seal member A can be directly attached to the underside of the top wall of the cap B. The cap B is preferably temporarily attached to the skin around the stoma 14 by a flexible membrane having a layer of skin compatible adhesive commonly referred to as faceplate 26. However, as will be shown below, it is preferable to incorporate means for removably attaching the cap B to the face plate 26 in order to avoid repeated removal of the adhesive member.

2, 3, and 4 illustrate a preferred embodiment of the ostomy device of the present invention. Although the present embodiment includes the balloon-shaped seal member A, the cap B, the adhesive means C, and the expansion means D as described above,
Further, an attachment means E for detachably attaching the cap B to the face plate 26, a waste collection container (disposal pouch) F, and
The expansion means G is also provided.

The mounting means E comprises a holding disk 16 and a base member 32. The mounting means E is the face plate 2
6, an annular projection or rib 34 extending from the surface of 6,
A first engaging portion is also provided.

The base member 32 has an annular shape and is provided with a second engaging portion composed of an annular channel 36. The base member 32 has a central opening 33 aligned with the stoma 14.

The rib 34 is fitted in the channel 36 in a detachable manner to form a liquid-tight seal between the face plate 26 and the base member 32. The first and second engaging portions may have the same form as that used in the conventional two-piece type ostomy device.

The side wall 38 of the cap B has an inward projection 40.
Is equipped with. On the other hand, the outer wall 42 of the base member 32 has a circumferential groove 44. The projection 40 is adapted to snap-fit into the circumferential groove 44 in order to fix the cap B to the base member 32. This is one possible configuration for releasably attaching the cap B to the base member 32, but many other configurations are readily available to one of ordinary skill in the art.

As shown in FIG. 5, the holding disk 16 is
It is located between the lower surface of the top wall 15 of the cap B and the base member 32. The holding disc 16 has a central opening 17 which is aligned with the opening 12 of the sealing member A. The portion of the wall 10 near the opening 12 of the seal member A is the holding disk 1
It is fixed at 6. When the cap B is attached to the base member 32, the wall body 10 of the seal member A is held and the opening 12 is covered.

The sealing member A is completely flexible, and by the expansion means G consisting of a flexible expansion tube 22,
It can be inserted into the stoma 14. The expansion tube 22 is located inside the seal member A, but is not attached to the wall body 10. The expansion tube 22 aids in the insertion of the seal member A into the stoma 14. Once the seal member A is inserted, the expansion tube 22 remains in place, but is small and flexible so that it does not cause irritating pain or discomfort to the user. Also, expansion tube 2
2 sends air through the internal expansion channel 24 to expand the seal member A.

As shown in FIG. 6, the external expansion valve 23
The seal can be pressurized by an expansion means D consisting of The nozzle 28 is inserted into the expansion tube 22 through the expansion port 20 of the cap B. Valve 23
Are squeezed to press the seal member A. The expansion tube 22 is connected to an internal check valve (not shown) in order to prevent air leakage from the rear of the seal member A. The pump constituting the expansion means D may be incorporated into the cap B to be an integral body.

Limiting the pressure applied to the seal member A is also a major concern. Our goal is to ensure that the sealing pressure exerted on the intestine or stoma does not exceed local capillary pressure to prevent necrosis of mucosal tissue. Therefore, a pressure relief valve 25 that opens at a pressure exceeding a predetermined limit is provided. Preferably, this relief valve 25 is incorporated in the expansion means D, such as the nozzle 28, and need not be provided in the device itself. The relief valve 25 prevents the seal member A from expanding too much.

The seal made of the seal member A is intentionally not a perfect seal. Mild irregularities in the intestinal wall and / or mild wrinkles formed in seal member A create very small leak paths. In fact, these leak paths are too small for solid or semi-solid stool to pass through, but allow the enteric gases present at the sealing surface to be released.

Once the intestinal gas has been released past the seal, one or more filtering elements 30 located in the retaining disk 16 are shown in FIGS. 4, 5 and 6.
Can be filtered by. The same activated carbon filters used in conventional ostomy pouches may be used for this purpose.

The cap B can be attached to the skin 18 around the stoma 14 by various means.
The means includes a layer of temporary skin compatible adhesive similar to the adhesive used to attach conventional one-piece ostomy pouches to the skin. However, as shown, the cap B is preferably associated with the face plate 26 of a standard two-piece ostomy device. The cap B is connected to the face plate 26 in the same manner as the two-piece type ostomy pouch. Since it is replaceable with a two-piece type ostomy pouch, as shown in FIG. 10, the user is always free to choose to use the excretion control device or a standard ostomy pouch.

As shown in FIG. 6, the side wall 38 of the cap B is shown.
The inward protrusion 40 on the inner surface of the outer surface 42 of the base member 32 is
It is fitted into the circumferential groove 44 of. The cap B is mounted over the base member 32 with the retaining disc 16 located therebetween. The cap B seals the opening 12 of the seal member A.

As shown in FIG. 7, when the cap B is removed, the intestinal contents need to be excreted and disposed of.
One means of facilitating disposal is to incorporate the disposal pouch F into the excretion control device.

The disposal pouch F preferably has a tubular form, is made of a thin, flexible plastic film and is concentric with the central axis of the ostomy device. The disposal pouch F includes a holding disk 16 and a base member 3
2 is attached to the opening 3 of the base member 32.
It has an opening lined with 3. The disposal pouch F is preferably folded into a thin annular space for storage in the ostomy device, as shown in FIG. It will be appreciated that many other alternatives are suitable for self-contained disposal pouches.

When there is a request for excretion, the user, as shown in FIG. 7, receives the base member 3 attached to the face plate 26.
2 is left, and the cap B is removed from the base member 32. One end of the disposal pouch F remains attached to the holding disk 16 and the other end remains attached to the base member 32. When the cap B is removed, the seal is opened, and the disposal pouch F spreads like a concertina bellows, and the excretion into the disposal pouch F becomes possible. When the contents of the intestines are released into the disposal pouch F as shown in FIG. 8, the base member 32 is removed from the face plate 26 as shown in FIG. Then, the assembly including the holding disk 16, the disposal pouch F, and the base member 32 is disposed in an appropriate waste container.

FIG. 10 shows a conventional two-piece type ostomy pouch 50. The pouch 50 is in the vicinity 5
It has walls 52, 54 sealed at 6. The pouch 50 includes an annular engagement member 58 having a channel 60. In the engaging member 58, the base member 32 is the face plate 2
It is adapted to engage the ribs 34 on the face plate 26 in the same manner as it is attached to the plate 6. Therefore, pouch 5
0 or the ostomy device of the present invention, the face plate 26
Can be installed on.

It is recognized that the present invention is directed to an elimination control ostomy device, which includes a balloon-like sealing member adapted to be received in the intestine and inflated to seal the stoma. It The device exerts minimal pressure on the tissue and is flexible and compliant, resulting in a comfortable means of controlling when excretion occurs. The inner expansion tube is provided to facilitate insertion and expansion of the seal member. A collection container is also provided as part of the ostomy device.

Although a limited number of preferred embodiments are disclosed by way of example, it will be apparent that many variations and modifications can be made to them.

As mentioned above, the basic aspect of the present invention is:
It is shown in FIG. The ostomy device of FIG. 1 includes a balloon-shaped seal member A, a cap B, an adhesive means C, and an expansion means D. The seal member A is inserted into the intestine and expanded to seal the stoma 14. The seal member A is made of a flexible wall body 10,

3 contacts the inner wall of the intestine. The cap B holds the seal member A and closes the opening 12. The cap B is attached to the face plate 26 constituting the bonding means C at its bottom edge. The seal member A is designed so that the nozzle 28 of the expansion means D is inserted into the seal member A from the expansion port 20 of the cap B and the valve 23 is squeezed so that air is sent and expanded. According to this ostomy device, the seal member A allows the stoma 14
The sealed state can be maintained by the cap means B. That is, excretion can be stopped while the cap means B is fixed. Therefore, the time of excretion can be controlled. Moreover, it can be controlled with a simple configuration.

And are equipped with. The bonding means C is composed of a face plate 26, and the face plate 26 has ribs 34 on the surface. The rib 34 constitutes the first engaging portion. The mounting means E includes a base member 32. The base member 32 has a channel 36. The channel 36 constitutes the second engaging portion. The base member 32 is detachably attached to the face plate 26 by the mutual engagement of the rib 34 and the channel 36. The cap B has a protrusion 40, while the base member 32 has a circumferential groove 44.
By fitting the protrusion 40 into the circumferential groove 44, the cap B is detachably attached to the base member 32. Therefore, the cap B is detachably attached to the face plate 26 by interposing the base member 32. Therefore, it can be said that the attachment means E is composed of the protrusion 40, the base member 32 having the circumferential groove 44 and the channel 36, and the rib 34. A holding disk 16 is present between the cap B and the base member 32.
